SUMMARY
The maximum number of 60.0 W light bulbs that can be connected to a 110V household circuit with a 20A limit is 36. This is calculated using the formula I = P/V, where each bulb draws approximately 0.545454A. Dividing the maximum current (20A) by the current per bulb results in 36.66666666, which rounds down to 36 bulbs. However, it is important to note that light bulbs may draw more power at startup, potentially tripping the circuit breaker if all are turned on simultaneously.
